This standard describes and specifies the minimum synchronization-rela

Synchronization-rela
Note that SONET NEs are not required to have an internal clock that meets the stratum level requirements as described in ATIS-0900101. This document defines the minimum performance specification for SONET signals at interfaces that are timed by SONET NEs with clocks that have free-run and holdover accuracies that are of lower quality than the stratum 3 level. Herein, these clocks are referred to as SONET minimum clocks (SMC). Some SONET NEs may be required, by either network operators or application, to support a minimum of stratum 3 level performance.
